I solved my problém with moving databases to memory - it reduces load on machine and now it is ok. But I am still experiencing gaps on some graphs. There is one device which suffers from it most - see attached graphs. (graphs are from 2 devices - one OK and the other with GAPS)
Gaps are only in port metrics graphs - they are at exactly the same time on all ports on given device.
Systém metrics are just fine on this device.
I checked the 5min graph of ipdevpoll systém metrics and it shows 100 at peak times, what I assume are only nearly 2 minutes.
I'm monitoring about 140 devices right now with nav.
I think that it is much correlated to my yesterday upgrade to 4.0.0 (from 4.0b5).
Since then I can also see attached errors. They were not there when I was on version 4.0b5.
It happens only on cisco catalyst 4500/6500 and one type of 3560E. (I have many 3750 but, there is no problém at all) and causes inventory jobs to fail.

Now I am able to collect all information needed.
But I still have a problém with collected data - there are very often gaps in graphs.
Which graphs have gaps? Port metrics? System metrics? All of them?
How many devices are you monitoring, and what does the runtime of the various ipdevpoll jobs look like?
If the 1minstats job is spending more than 1 minute to complete for any device, there may be gaps its graphs, 5 minutes for the 5minstats job.
